* Featured by Apple in the United States in Productivity > New & Noteworthy

The Concrete Calculator+ app consists of calculators and solvers to help contractors and sales people estimate costs, sizes, and materials amount as well as prices.

• Concrete Bags
• Concrete Footings
• Concrete Rectangle
• Concrete Sono Tube

The Water Collection and Rainfall calculators are designed to calculate the potential and factored water supply of any given enclosure by measuring the interior for the collection of water using length, width, and depth in feet, inches, or meters. The surface area is calculated in square feet, square inches, square yards, and square meters, as well as the potential and estimated actual recovery volume is given in cubic feet, cubic meters, gallons, quarts, and liters.

Water may be collected from any surface, and this app assumes a rectangular enclosure and a constant depth where the water is stored to allow use at a later time for non-drinking water utility, for example, flowers and lawns. Because of direct loss and other factors, such as evaporation, there is a percentage of the actual potential that is very close for collected water volume. In moist cool areas, that may be in the range of 85%, or in the case of dry, hot, desert conditions, it is closer to 60%.

Time Value of Money

* Featured by Apple under ‘What’s Hot’ in United States under iPad > Finance

Universal Application for iPad, iPhone and iPod touch.

The Time Value of Money is an App which will help you figure out the value of money figuring in a given amount of interest earned over a given amount of time. The idea is that money made available at the present is worth more than the same amount of money in the future due to its potential earning capacity through interest. Provided this money can earn interest, any amount of money is worth more the sooner it is received.

This App specifically concentrates on solving for

1) Present Value (PV),
2) Future Value (FV),
3) Periodic Payment Amount (PMT),
4) Number of Compounding Periods (Time), and
5) Interest Rate (Rate(%))

For example, Compound Annual Growth Rate (CAGR) can be computed by selecting “%” and entering 3 numbers: PV, FV, and Time, then selecting Annual.

This app has built-in reference with equations.

This app features:

• Send your calculations or conversions by email
• Universal App (iPhone, iPod Touch, and iPad)
• Latest version of iOS is supported
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs
• Export to CSV
• iPhone 6, 6+, 5 screens and the original 3.5 inch screen are supported
• Latest version of iOS is supported

No network connectivity required.

This app is available for a discount to Apple-approved Education institutions through the Apple’s Volume Purchase Program.

Plumbing & HVAC Calculators

Posted by The Department on August 4, 2010 Comments Off

The Plumbing & HVAC Calculators & Converters app is good for reference, educational, and small projects.

Calculators

1. Weights (Ounces, Grams, Pounds, Tons US, Kilograms, Tons UK, and Tonnes
2. Virtual Airflow (US Units)
3. Virtual Airflow (Metric Units)
4. Reynolds Number for Metric
5. Reynolds Numberfor US / Imperial

The Virtual Airflow & Reynolds Number calculators are designed to give related and relevant information about the amount of air in a defined area, and the size air handler or fan required to move it in a given amount of time. The air movement can be from a heater, AC unit, chiller, refrigeration unit, closed fan unit or cooler (swamp cooler or evaporative cooler) into the area, or from an exhaust fan moving the air out of the area.

For the distance calculators enter the area dimensions in feet or meters. Accuracy to the inch or centimeter is not needed. Enter the number of times per hour that you would like total change of the air mass volume in that area. Enter the air flow specification of the air handler (fan) you anticipate using in cubic feet per minute (CFM) or cubic meters per minute. Click on Calculate and the results will be the (air) volume of the area, the amount of time for each volume of air mass change, the total volume of air requiring movement with an hour, the volume air flow of the suggested fan (based on your entries) and the number of fans or air handlers needed if they are of the target size you selected.

A guideline for clear air (especially if filtered) in an area is 4 to 8 complete cycles every hour.

Area Converters

• Square Inches and Shorter Conversion
• Square Feet & Yards & Meters Conversion

Distance Converters

• Inches & Centimeters & Millimeters Conversion
• Feet & Yards & Meters Conversion
• Miles & Kilometers Conversion

Volume Converters

• Metric to US/Imperial Units Conversion
• Inches & Centimeters Volume Conversion
• Feet, Yards, & Meters Volume Conversion

All results can also be emailed through the iphone’s email application using an automatically filled-in email template provided with the app.

Note: Should not be considered for open fan blade fans in ceilings higher than 12 feet or with fan’s rated or measured in capacity for a room size in square feet rather than cubic feet.
